fitting 3 sets of data simultaneously using "lsqcurvefit"

I have a set of data in triplicates (attached). I want to fit the exponential part of these 3 sets simultaneously using "lsqcurvefit" and get one x(1) and x(2). I have included "t" and "or" data in the attached file and here is my function:
function y=or(x,t)
y=((0.282*x(2))-0.24)*x(1)*exp((x(2)-0.24)*t)
I managed to fit each data set individually and average x(1) and x(2) and calculte the STdev but if I could fit 3 sets simultenausly using "lsqcurvefit" would be better.
I would be grateful if you kindly help me.

Define
T = [t1;t2;t3]
and
OR = [or1;or2;o3]
and treat
[T,OR]
just like you treated
[t1;or1],[t2;or2],[t3;or3]
.
What's the problem ?
